What problem does it solve? Errors in Node.js services often go uncaptured or are logged only to the console, making production failures invisible and hard to diagnose. This Skill enforces consistent Sentry v8 error capture and performance monitoring patterns across controllers, routes, cron jobs, workflows, and database operations. ## Core Features & Use Cases - Standardized Error Capture: Provides copy-ready patterns for controllers (BaseController), Express routes, workflows (WorkflowSentryHelper), and cron jobs with mandatory instrument.ts imports. - Performance Monitoring: Instruments database queries with slow-query thresholds, N+1 detection, and Sentry spans for async operations and cron execution time. - Use Case: When adding a new cron job to an email service, follow the mandatory pattern that imports instrument.ts first, wraps execution in a Sentry span, and captures exceptions with cron-specific tags before exiting. ## Quick Start Add Sentry error tracking to my new Express route following the error-tracking skill patterns.
